A nurse is assessing a 1-month-old infant at a pediatric office. Which of the following findings requires a referral for further care?
Limited hip abduction
Equal leg length
Symmetric gluteal and thigh skin folds
Femoral head remains in the acetabulum during the Barlow maneuver
The Correct Answer is A
Rationale:
A. Limited hip abduction: Limited abduction of the hips in a 1-month-old can indicate developmental dysplasia of the hip (DDH). This finding warrants further evaluation, such as ultrasound imaging, to rule out structural abnormalities and initiate early treatment if needed.
B. Equal leg length: Equal leg length is a normal finding and does not require intervention. Leg length discrepancies are more concerning and often associated with hip dislocation or other musculoskeletal conditions.
C. Symmetric gluteal and thigh skin folds: Symmetry in the gluteal and thigh folds is a reassuring sign that typically rules out DDH. Asymmetry would be more suggestive of a hip abnormality requiring follow-up.
D. Femoral head remains in the acetabulum during the Barlow maneuver: This is a normal finding. The Barlow test assesses for hip instability, and if the femoral head remains stable within the socket, no further evaluation is needed.

Correct Answer is B
Explanation
Rationale:
A. Troponin level: Troponin is a cardiac biomarker used to detect myocardial injury or infarction. It is not an indicator of nutritional status and does not reflect protein levels or nutrient balance.
B. Serum albumin: Albumin is a plasma protein synthesized in the liver and commonly used as a marker of long-term nutritional status. Low levels may suggest protein-energy malnutrition or chronic illness affecting nutrient absorption or intake.
C. Erythrocyte sedimentation rate: ESR is a nonspecific marker of inflammation or infection. While chronic disease can indirectly affect nutrition, ESR does not directly assess nutrient levels or dietary sufficiency.
D. Serum sodium: Sodium levels reflect fluid balance and electrolyte status but are not indicators of nutritional status. They may be influenced by hydration, renal function, or hormonal imbalances, not by dietary protein intake.
Correct Answer is C
Explanation
Rationale:
A. "Your child can return to school once the fever has subsided.": The absence of fever does not indicate the child is no longer contagious. The child can still transmit the varicella-zoster virus until all lesions have crusted, even if fever has resolved.
B. "Your child can return to school after a negative titer result.": Titer testing is not used to determine contagiousness in active varicella infection. It is typically used to confirm immunity, especially after vaccination or past exposure.
C. "Your child can return to school once the lesions have crusted over.": Varicella is contagious until all lesions have crusted, which usually occurs about 5–7 days after the onset of rash. Crusting marks the end of the infectious period, making it safe for the child to return to school.
D. "Your child can return to school 24 hours after beginning antibiotics.": Varicella is a viral illness, not treated with antibiotics unless there is a secondary bacterial infection. Antibiotics do not impact the contagious period of the viral illness.
